Successful Slow Pathway Modification with Radiofrequency Ablation in a Patient with AVNRT and Congenital IVC Continuity with Azygos Vein.
Background: Congenital anomalies of the inferior vena cava (IVC), such as interrupted or azygos continuation, complicate catheter-based procedures like atrioventricular nodal reentrant tachycardia (AVNRT) ablation. Understanding IVC variations is crucial for successful outcomes in interventional cardiology.
Case presentation: A 57-year-old male with long-standing paroxysmal atrial fibrillation (AF) underwent successful catheter ablation for AVNRT. Intra-procedurally, a congenital IVC anomaly was identified, requiring modified vascular access.
Conclusion: Recognizing IVC anomalies and adapting access strategies are key to overcoming procedural challenges and ensuring successful ablation outcomes. Comprehensive imaging and planning are vital for managing patients with IVC variations.
Learning points: Congenital inferior vena cava (IVC) anomalies, including azygos continuation, can complicate catheter-based interventions such as ablation of atrioventricular nodal reentrant tachycardia.Congenital anomalies of IVC are rare but critical considerations for atrioventricular nodal reentry tachycardia (AVNRT) ablation procedures.Understanding these variations is essential for ensuring successful catheter-based interventions and minimizing the risk of complications.
期刊介绍：
The European Journal of Case Reports in Internal Medicine is an official journal of the European Federation of Internal Medicine (EFIM), representing 35 national societies from 33 European countries. The Journal''s mission is to promote the best medical practice and innovation in the field of acute and general medicine. It also provides a forum for internal medicine doctors where they can share new approaches with the aim of improving diagnostic and clinical skills in this field. EJCRIM welcomes high-quality case reports describing unusual or complex cases that an internist may encounter in everyday practice. The cases should either demonstrate the appropriateness of a diagnostic/therapeutic approach, describe a new procedure or maneuver, or show unusual manifestations of a disease or unexpected reactions. The Journal only accepts and publishes those case reports whose learning points provide new insight and/or contribute to advancing medical knowledge both in terms of diagnostics and therapeutic approaches. Case reports of medical errors, therefore, are also welcome as long as they provide innovative measures on how to prevent them in the current practice (Instructive Errors). The Journal may also consider brief and reasoned reports on issues relevant to the practice of Internal Medicine, as well as Abstracts submitted to the scientific meetings of acknowledged medical societies.
